Our son had the procedure done just before his first birthday (Sept 2011 .) I believe his sedation was just as Mellie Mel described above. I was worried about that, too.

Just an FYI, if your LO does have the procedure (and I'm sure they would tell you this, but it never hurts to be well informed...) your LO will be STARVING and thirsty when they get into recovery, so pack a lot of snacks and drinks for them. They aren't allowed to eat before the procedure. Also, that is a good reason to schedule the surgery first thing in the morning. It was so hard not to give our LO something to eat or drink that morning

I was a nervous wreck and very disheartened about him having the procedure. However, it was done SUPER quickly and it was so nice to finally have him "cleared up" after. I always felt bad seeing him with his watery eye. Good luck, Mama!

They just had him breathe the gas. From the time they took him back until the doctor came and talked to us is was 9 minutes. Within 15 minutes he was awake and we left the hospital 42 minutes from the start of his procedure. He did fantastic. No nausea. Not fussy. Instantly no more icky eye :)
